Metal Nadcc Tablets For Swimming Pool

Precure "T 90 For Swimming Pool Disinfectantation TRICHLORO ISOCYANURIC ACID (TCCA) Granules and 200 GM Tablets DISCRIPTION: Precure "T 90 is excellent source of chlorine for the control of biofouling in swimming pools, industrial water systems and cooling water systems. Precure "T 90 has been proved to be a better and more economical alternative to bleaching powder and sodium hypochlorite for all kind of chlorination applications. PROPERTIES: Chemical Name: Trichloroisocyanuric acid Formula: C3O3N3CI3 CAS Number: 87901 Molecular Weight: 232.4 Appearance: white powder or granules Effective chlorine: >90.0% PH (1% soln): 2.7 to 3.3 Moisture: 0.5% max. Solubility at 25 C: 1.2 (gm / 100 gm water) Chemistry of PRECURE T 90 After hydrolysis in water, Precure T 90 will be converted to hypochorous acid (HOCCL), which has strong microbial activity. The hydrolysis byproduct, cyanuric acid, acts as a stabilizer and prevents conversion of hypochlorous acid into hypochlorite ion (OCL) owing to sunshine and heat, which has low microbial activity. Advantages of PRECURE T 90 Cost effective and stable source of chlorineEasy to handle, ship, store and apply. Save expensive cost of equipments.No white turbidity (as in case of bleaching powder)Long duration of sterilizing effectStable in storage long shelf life. Applications: Disinfection of civil sanitation and waterDisinfection of swimming poolsDisinfection of industrial water pretreatmentsOxidizing microbiocide for cooling water systemsBleaching agent for cotton, gunning, chemical fabricsAnimal husbandry and plant protectionAs anti shrink agent for woolens and battery materialsAs deodorizer in distilleriesAs preservative in horticulture and aquaculture industries. Handling Keep the container closed when not in use. Store in cool, dry and well ventilated area, away from fire and heat. Use dry, clean clothing when handling Precure T 90 breathing dust, and do not bring in contact with eyes or skin. Wear rubber or plastic gloves and safety glasses. Packing Precure T90 is available in 50 kg HDPE drums Users Guide Recommendations for Pool Treatment The most important water quality parameter to maintain in a swimming pool is the free chlorine level. The free chorine concentration should always be over 1.0 ppm (mg/L) to keep bacteria under control. We normally recommend about 3 4 ppm, as this level is required to control both bacteria and algae. The higher level is particularly recommended if Procure T90 (TCCA) is being used. The other important water quality parameters to be maintained are pH and total alkalinity. The pH should be kept in the range of 7.2 7.6. Lower PH lead to corrosion of piping and attacks pools walls (plaster, tile grout, etc.) Higher PH reduces the effectiveness of the chlorine. This is also the PH which is best for the swimmers. Precure T 90 (TCCA 90) is acid, so over the time it can slowly decrease the pH. The pH should be checked routinely and if it drops below 7.2 , some soda ash (sodium carbonate) should be added to raise the pH back to the recommended level. The total alkalinity should be maintained in the range of 80 125 ppm. Alkalinity (also known as pH buffer) limits how fast the pH changes when acid or caustic are added to the water. Soda ash also adds alkalinity. The National spa & Pool Institute (USE), a swimming pool and spa industry organization, has developed a number of standards for design and use table below. click http://www.nspi.org for more information.
